Answer:

7.85sec

Step-by-step explanation:

Given that,

s(t)=16t squared​, where t is time in seconds. The height of a certain tower is 986 feet.

s(t) = 16t²

so when s = 986feet

16t² = 986 feet

t² = 986 /  16

t² = 61.625

t = √61.625

t= 7.85 seconds

Answer: t = 7.85seconds

Step-by-step explanation:

Given that :

Height of tower = 986 Feets

Function s(t) = 16t^2

To find the time t 8 in Seconds taken for an object to fall to the ground from the top of the​ building

16t^2 = 986

t^2 = 986/16

t ^2 = 61.625

Take the square root of both sides

t = sqrt(61.625)

t = 7.85seconds

what is the slope- intercept form of the equation of the line that passes through the points (-3,2) and(1,5)
erma4kov [3.2K]

Answer:

y = \frac{3}{4} x + \frac{17}{4}

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (1, 5)

m = \frac{5-2}{1+3} = \frac{3}{4}, hence

y = \frac{3}{4} x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (1, 5 ), then

5 = \frac{3}{4} + c ⇒ c = 5 - \frac{3}{4} = \frac{17}{4}

y = \frac{3}{4} x + \frac{17}{4} ← in slope-intercept form

Alvin is 14 years older than Elga. The sum of their ages is 56. What is Elga's age?
uysha [10]

Answer:

Elga is 32 years old.

Step-by-step explanation:

Let Alvin's age = A

Let Elga's age = E

 

Alvin is 10 years younger than Elga, so A = E - 10

The sum of their ages is 54, so A + E = 54

 

Replace the A in the second equation with E - 10, then solve for E.

A + E = 54 becomes (E - 10) + E = 54

 

Combine like terms

2E - 10 = 54

 

Add 10 to both sides

2E = 64

 

Divide both sides by 2

E = 32

Combining like terms: -7x+x HELP ASAP​
Svetllana [295]

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

When you combine like terms you see the ones that are similar then you add or subtract, depends on what the signs are. For this one -7x is similar to x so in this case you would add x to the -7x which will give you -6x.
